The Patient as Instrument Stand – A Time-Motion Study of Sub-optimal Instrument Placement
Background: When not in use, instruments are sometimes placed on top of the patient’s body during laparoscopic procedures. Such instrument “hoarding” has been previously mentioned as a non-optimal practice. Ergonomic design of surgical workplaces may improve efficiency while maintaining safety. However, no studies have been carried out to describe where instruments are placed during surgery.… Continue Reading

Eliminating Paradoxical Imaging During Laparoscopic Surgery in the Age of Head-Mounted Display
BACKGROUND: Complex laparoscopic tasks are nearly impossible to complete when the telescope is pointed toward the operator (paradoxical image). Attempts at image manipulation have been reported, but altered monitor displays may introduce even more confusion. The availability of high-quality, lightweight head-mounted displays (HMD) now allows individualization of the laparoscopic image. We sought to demonstrate that… Continue Reading

Minimal Thermal Effects of a Continuous Power Delivery System with Bipolar Sealing Capability As Measured By High Definition Thermography
Objective of the study: Evaluate the real time thermal footprint of a continuous power delivery technique with bipolar sealing technology as measured by high-definition thermography. Description of the methods: Thermography is the use of an infrared imaging camera to record the radiating heat in real time, as thermal energy is emitted from an object. In… Continue Reading

Better Performance of Laparoscopic Simulator Tasks with High Definition Camera Technology: A Pilot Study
Background: The availability of a High Definition (HD) laparoscopic camera improves image quality, however whether this translates into improved performance compared to a standard camera (SD) is not known. We investigated whether performance in a laparoscopic simulator would be affected by the use of a HD camera.Methods: 5 subjects (2 surgical residents and 3 laparoscopic… Continue Reading
